4 Claims.

This invention relates totheprinting art and especially to theoperationoftransferring th socalled form'from the'bed ofthe press onto atable (as for changing the type) or reversely. The press-bed and tableare frequently somewhat spaced apartand have their surfaces more or lessflush with each other. The form comprises a rectangular frame or chasein which the sheet of type is held by so-called quoins or adjustableclamps interposed -between each of the foursides-of the type-sheetandthe corresponding side ofthe-chase. "In order to pull the heavy formfrom the press-bed onto the table the operator entershis fingers througha slot-like space existing betweenone side'of tthe'chase and thetype-sheet, which frequently results in his fingers being pinched orcrushed between the form and the table due .totheir'then projectingbelow the under surface of the form and thus opposed by the table;frequently the resulting injury to the operator is serious.

According to this invention .1 provide what I term a form-puller whichis so constructed and its parts so formed as to adapt it to beeffectively interlocked with the form xdirectly engaging one of thequoins thereof, the implement having'a handle to be gripped by theoperators hand and which, when theimplement islinoperativestate, ispositioned well and hence safely above the form.

In the drawing,

Fig. 1 is a fragmentary plan view of a pressbed and table and a form-onthe press-bedto be shifted onto the table by the implement, appearing asviewedzin plan;

Fig. 2 is mainly a section'on -line22, Fig. 1, and on a'larger. scale;

Fig. 3 is an elevation of the implement as seen from thezright in Fig.2; and

' Figs. 4 and 5 are respectively an end-view of a quoin and a section ofthe latter on line 5-5, Fig. 1.

The form comprises the usual frame or'chase i, the sheet of type 2within the chase (they being as usual rectangular as would appear wereeach'shown infull), and th usual quoins (to'be described) .at least twoof which usually occupy a slot at existing between any margin of thetype-sheet and the corresponding side of the chase. Each quoin or clampcomprises a pair of elongated wedges 3 which, as assembled, .have outerplaniform sides 3a and are each formed at the inner side thereof with alongitudinal'median tongue 32:, the tongue of either wedge being engagedin a groove of a riser 3d'of th other wedge and eachhaving at each sideof its tongue a row of teeth 36, the teeth of both wedges being adaptedto be engaged by a rotary :key (not shown) "for displacing themlengthwise in opposite'directions relatively to each other. Asuitablenumber of the quoins being positioned in each slot, by the key they aremade to exert wedgingaction'on the type-sheet and 'chaseso that theresulting unitary structure constituting the form-is produced.

At A is the bed of the press and at B is the table onto which the formis to bedisplaced.

(InsFig. l the'sheet of type'is shown only in iagrammatic outline, thetype being individually delineated, however, in Fig.2.)

'Theforrn-puller of this invention is'formed according to the-exampleshown asfollows:

There is aa block 4 whichin plan is oblong and has its bottom surfaceperpendicular to its upright sides. A'circumferential groove 4a isformed in the block in parallel relation to said bottom surface and itprovides an upwardly facing shoulderib.

Extending downwardly into the block is a stem 5 forming a handle andwhich is in threaded engagement therewith and may be rotated therein, Atthe free end of the stem is a bar Gaforming a handle proper extendingtransversely of the upright threaded end portion of the stem, the latterbeing preferably bent, as at to, substantially ata right angle and thusappearing T-shaped in plan.

On the threaded portion of the stem is screwed a lock-nut I, here of thewinged type. It-is to serve releasably to bind the stem to theblockagainst rotation.

Whereas any slot a may vary in width, wherefore each quoin isconstructed so as to be operative onthe wedge-like principle, thespacing (to be referred to) at afldetermined by the dimension of lariser Ed, is of course invariable whatever-may bethe adjustment of thequoin. But frequently a slot 0. may exist of such width'that by noadjustment would a quoin having given dimensions, such as those-shown inthe present drawing, be serviceable, wherefore the operator usually hasavailable another quoin of small size, with the consequence, of course,that the spacingsa of the'two quoins are unequal.

Having these circumstances in mind, the block and stem of the presentimplement are "to be secured together by thelock-nut so that the bar 6may be approximately parallel with eitherthe transverse axis --or thelongitudinal axis of the block, depending onhow the blo'ck'is enterableto the available space a existing between a projection such as 3.1: of aquoin and a surface of the form opposed to such projection and, whensuch entering is effected, on whether or not an effective interlockbetween the form and formpuller may be accomplished by the shoulder 4bengaging the tongue of such projection. In Figs. 1 and 2 in view of thesize of the quoin shown the block has been entered to such space withits transverse axis extending lengthwise of the slot a. But if the spaceat a were narrower, due to resort to a smaller quoin, the block couldnot be entered to said space with its tranverse axis so extending. Inthat case, since the block would have to be entered with itslongitudinal aXis extending lengthwise of the slot, the handle is to beadjusted 90 from its shown position, or so as to be approximatelyparallel to the longitudinal axis of the block, that is, by releasingthe lock-nut, effecting the necessary relative rotation as between theblock and handle, and resettin the lock-nut in binding position.

The implement is shown in interengaged relation to a projection 31:which is relatively remote from and whose tongue 3b projects toward thetable. It might, however, be interengaged with a projection 39: (as atthe opposite end of the quoin which adjoins the table in Fig. 1) whosetongue projects away from the table. Since the implement might be usablein one of these positions and immediately thereafter in the other it isof advantage to have the shoulder 41) exist at both of the long andshort sides of the block.

Essential features of my invention include a block substantially oblongin plan and having an upwardly facing shoulder, as M), at each of atleast two upright sides of the block which adjoin each other and a stemupstanding from the block and rotative relatively thereto around anupright axis and having above the block a transversely extending handle.With the implement so constructed upon 90 rotative adjustment of thestem relatively to the block the implement can be operatively engaged insuch a space as a whether the same be of the wide or narrow dimensionaccording to the size of quoin which was required to be used. Butpreferably, the mentioned shoulder extends circumferentially of theblock Whereby the implement can obviously be applied to a space a havingeither the wide or narrow dimension and whether located at the left-handor right-hand end of the quoin.

Having thus fully described my invention what I claim is:
